To all whom it may concern:

Be it known that I, WILLIAM A. Rmnom, Sn, a citizen of the United States, residing at Oshkosh, in the county of Winnebago and State of Wisconsin, have invented certain new and useful improvements in Brake-Setting Mechanisms; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to brake setting mechanism for engines or motors which are actuated by steam or electricity, and it has for its object to provide means whereby when a signal has been displayed at any point and the motor or engine is not stopped by the engineer or other person in charge, the brake setting mechanism is automatically thrown into operation; and where the car or engine is being driven by electrical power, the circuit for such power is automatically and simultaneously broken at the time that the brake setting mechanism is operated.

. In the accompanying drawings, which illustrate an embodiment of the invention: Figure 1 is a diagrammatic view of mechanism by which the invention may be practiced; Fig. 2 is an enlarged side elevation of the means for automatically setting the brake mechanism in operation; Fig. 3 is a front View of said mechanism. Fig. t is a vertical section taken on the plane indicated by the dotted lines 4% of Fig. 3, and Fig. 5 is a transverse section taken on the plane indicated by the dotted lines 5-5 of F i 3.

Referring more particularly to the drawings, 1 indicates a car-.which in the present instance is shown as being electrically driven, although it can be propelled by steam or other motive power with the same results so far as brake setting mechanism is concerned. Located adjacent to the track 2 are suit-. able signal stations 3, only one of which is shown, which may be of any desired construction. In each of said stations or signals a circuit closer, as a roller 4 provided with a segment 5 or other means for closing a cir-v cuit, is adapted to be actuated by the signal setting mechanism which can be driven b means of a current from line wires 6 and or otherwise.

Two wires 8 and 9 are adapted to be en gaged by the contact or segment 5, whereby a circuit may be completed through them. One of the wires, as 9, is connected with one or both of the track rails 2 and wire 8 is connected with an insulated rail 10 which is located at any point convenient to the track railsQ, it being shown midway between them in the drawing, but it is evident that it could be located at either side of them with equal eiiiciency.

The car 1 is provided witha battery 11, of any suitable kind, one side of which is connected with the car wheels through the wire 12, and the other side is connected with a brush 13 through a wire 14. is adapted to engage with the third rail 10 as the car passes over it, and thereby com plete roller 4.- has been rotated so as to cause the contact 5 to engage with the wire 9 and he brush 13 a circuit through the battery the.

thereby complete the circuit from wire 6 and 13, except when it is desired that the car be stopped at the station.

To insure that the car should stop at the station when the signal is given in this manner, means arcprovided for automatically opening the air valve, 16, of the brake settin mechanism, 17, and thereby ermit the bradcos to be automatically applied and thus bringozhe car to a standstill. The valve 16 may actuated in any desired manner, but I refer to control it by means of a lever, 1% w ich is normally heldagainst the action oi a s irng, 19, by a catch, as a hook, 20, on one on of a pivot lever, 21. The lever 21 is adapted to be actuated to release the lever or handle 18 by means of an upward movement of the core 22 of an electro-magnet 23 which is connected with the wire 14.

By constructing and arranging the parts in this-manner, it is evident that as soon as a circuit is completed through the brush 13 and contact 5, the coil 23 will be energized and the core 22 moved lon itudinally so as to actuate the lever 21 an thereby release the handle 18 from the catch 20 when the tion of the brakes at the desiredd'egree of '25 wire 32.

ordinary manner.

posed exteriorly threaded exhaust pipe or gage with the terminals 31 of the wire 3:2

spring 19 will immediately throw the lever 18 forward and thus open the valve 16 and permit the application of the brake 17 in the Said Valve member em braces a central upright casing 24 formed with upright and depending exteriorly threaded pipes or stems 25 and 26, respectively, the former being adapted for connection with a suitable, source of pressure and the latter with the brake or train pipe.- Said casing is also provided with an obliquely disstem 27 to which is adapted to be screwed a relief valve :28 of any well own type or pattern. l

A valve member 29 is arranged to work in the casing to cutofi' the supply of pressure when it would be desirable to effect an application of the brakes, the relief valve being regulated to permit the outflow of the pressure fluid through the exhaust pipe until the desired reduction of pressure in the train pipe has been secured to cause the applicapressure. Said valve member is provided with a small port 29 to allow enough of the pressure fluid to pass through to compensate for theleakage in the train pipe. r 1' Vhen it is desired to release the brake mechanism as whentit is safe for the car 1 to go forward and the contact 5 has been moved out of engagement with the wires 8 and 9 with the movement of the signal 15 the handle 18 is drawn backinto engagement with the catch 20 and is held in that position until after the circuit has been again completed through the battery 11 and the electro-magnet has been energized so as to release the catch 20 from the handle 18, which will again cause'the brake mechanism to be actuated as above described.

Where the car is electrically driven, as shown in the drawin s, the handle 18 is provided with means for automatically breaking the circuit from the main wire when the handle is thrown forward by the spring 19. In the drawingsI have shown such means as comprising a switch member 30 secured to the handle in position for its ends to enleading from the line wire 6 to the dynamo 33, and from there to the car wheel 3% and back to the line wire 7 through the track wire The switch member 30 is preferably formed as a laminatedspring of copper, with'its ends adapted to be forcibly engaged with gthe contact points 31 of the By providing the handle with means for automatically' breaking the circuit simultaneously with the opening of the valve to control /the brake mechanism, it is evident that itgwould be absolutely impossible for an electrically driven car to pass beyond any point,'or station in which means were pro manually.

Having thus described my inventiomwhat I claim as new and desire to secure by Letters-Pa'tent, is t 1. In apparatus of the class described, a cut-oft; valve adapted for communication with a source of pressure fluid and the brake or train pipe, a lever to hold'said valve in normalposition to permit the passage of the pressure fluid to the train pipe, an electric circuit including an electric magnet to release said lever, and a release valve communicating with the cut-o? valve to regulate the pressure within the brake pipe after cutting oil the supply of pressure to the same.

2. In an apparatus of the class specified a cut-oil valve adapted for communication at one end with a source of pressure fluid and at its opposite end with the brake or train pipe, a spring pressed lever connected with the cut-oil valve, locking means for cut-off valve and adapted to be regulated to permit the escape of the pressure fluid from the brake pipe when the lever is-released until the desired reduction of the pressure of the fluid within the pipe has been secured.

3. In apparatus of the class specified the combination of a car, a track, a track con tact, a cut-off valve on the car, an electrictripping magnet on the car, a spring pressed lever adapted to operate the valve, a latch device for locking the lever in normal position to permit the passage of the pressure through the valve, a circuit including the magnet and one rail of the track, to energize the magnet and release the lever to operate the valve to cut off the supply of pressure-fluid through the same, and a relief valve communicating with the cut-01f valve and adapted to be regulated to permit the escape of pressure fluid from the train on; brake pipeuntil the desired reduction of) pressure of the fluid within the same is secured.
